Jon, I can answer the SDO/EMF bit of your question. The short answer is that EMF is an implementation dependency of our SDO implementation which unless you have some particular requirement that the SDO 2 spec doesnt cover, then you don't need to worry about it. The longer answer is that the eclipse implementation of SDO 1 is based upon EMF, and the SDO 1 spec effort had two classes of programmer in mind, those who dealt with the getting and setting values on the graph, and those who created graphs and dealt with back end stores (Data Access Service programmers). The SDO 1 API only claimed to support the first class of programmer, and the DAS programmers would need to get down and dirty with the facilities offered by the implementation (i.e. EMF for the Eclipse SDO). SDO 2 is considerably more mature, and the Tuscany implementation has its SDOUtil class to try to plug any gaps that are found in the SDO 2 spec (any such gaps being fed back into the 2.1 and 3.0 spec efforts). So at the moment there are a number of people who developed code against SDO 1 who are figuring out how the SDO 2 API handles those things they had previously done in EMF, but as you are a newbie I guess you don't fit into that category. My suggestion to you is that you just focus on the SDO API, and consider EMF as something under the hood that you can forget about. If you do find something that you can't do with SDO or with our SDOUtil class then if you could feed back the issue to us that would be great.
